The Working Principle Of Gate Valve

Aug 15, 2017

     Gate Valve headstock is the gate, the movement direction of the gate and the direction of the fluid, the gate valve can only be open and full off, can not be adjusted and throttling. The gate has two sealing surfaces, the most commonly used mode gate valve two seals form the wedge shape, the wedge angle with the valve parameter and the different, usually is 5 °, the medium temperature is not high when 2°52 '. Gate Valve
     The wedge-type gate valve can be made into a whole, called a rigid gate plate, can also be made to produce micro-deformation of the brake board to improve its process, to make up for the sealing surface angle in the process of the deviation generated, this kind of gate is called the Elastic Gate plate. When the gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, depending on the medium pressure to press the sealing surface of the brake plate to the other side of the valve seat to ensure sealing surface, this is the self sealing.Gate Valve
     When the gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is to rely on the medium z41h flange wedge-type gate valve pressure to pressure the gate seal face to the other side of the valve seat to ensure the sealing surface, this is the self sealing. Most of the gate valves are forced seal, that is, when the valve is closed, it is necessary to force the gate to be pressed to the seat by external forces to ensure sealing of the seal surface.Gate ValveGate Valve
     Movement mode: Gate valve of the gate with the valve stem for a straight line movement, also known as the Ming rod gate valve. Usually, there is a trapezoidal thread on the lifter, through the nut on the top of the valve and the guide groove on the valve body, turning the rotation movement into a straight line motion, that is, turning the operation torque into operational thrust. When opening the valve, when the gate lifting height is equal to the valve diameter of 1:1 time times, the flow of the channel is fully unblocked, but at run time, this location is not monitored.Gate Valve
     Manual Gate Valve Working principle: Turn the wheel, through the handwheel with the stem of the thread of the inlet, retreat, lift or drop with the valve stem connected to the valve plate, to open and close the role. According to the shell/main material classification, gate valve can be divided into: metal material valves: such as carbon steel valves, alloy steel valves, stainless steel valves, cast iron valves, titanium alloy valves, Monel valves, copper alloy valves, lead alloy valves. Metal body lining valve: such as lined rubber valves, lined with fluorine valves, lined with lead valves, lined with plastic valves, lined with enamel valves. Non-metallic materials valves: such as ceramic valves, glass valves, plastic valves.Gate Valve     Gate Valve headstock is the gate, the movement direction of the gate and the direction of the fluid, the gate valve can only be open and full off, can not be adjusted and throttling.
